Bosch Combi-Drills - a Toolstop Buying Guide
Posted by Mark Hunter - July 10, 2013
We love helping you guys out decide which power tools are best for the jobs you need to do each day. Buying new power tools is always an investment, so we want you to know what you're getting for your hard-earned cash.
We're covering 3 combi-drills in Bosch's blue professional stable, we'll take you through each one, giving you the spec, the special features and who each drill is ideal for.
This combi-drill, referred to as part of the "Light Series" is all about ergonomics. There's a compromise in power, but that transfers over onto the size and weight of the drill thanks to its small diameter motor.
If you're a plumber or electrician and need a combi-drill that won't tire your arms or shoulders out when working overhead throughout the day, or in tight spaces, then this is well worth a look.

The Dynmamic Series combi-drill has a beefier motor, Bosch's new 4-pole version. This provides you with grunt and over-all reliability, which is what you expect and want from a quality combi-drill.
The tool still offers great ergonomics, being - according to Bosch - the shortest head length in class at a diminutive 195mm.
The weight, with the battery fitted, is only 1.9kg, so again it's a great combi-drill for working at above shoulder height.
A great feature of this combi-drill is that it now comes with 4Ah CoolPack batteries which Bosch is claiming will over your up to 60% longer run-time per charge.

|Bosch Electronic Cell Protection (ECP)
||Impact rate: 0-25,500 per minute
|The shortest 18 volt long-distance runner with impact drilling function
||Max Torque hard /soft joint: 67/28 Nm
Max. drilling diameter in wood: 35 mm

This is Bosch's top of the range combi-drill and here's why; maximum torque of 85Nm, capable of drilling 14mm into masonry, and able to withstand a drop of 2m onto concrete.
As above, this is now shipped with the 4Ah CoolPack batteries that'll protect your tool while you work.
Basically this combi-drill is a great tool for heavy duty work, but - and we've had this confirmed (click here) - it doesn't compromise on weight.
